Abstract
Strips, particularly test strips and adapters for test strips, for use in meters for the electrochemical measurement of analyte in a sample material and in particular the glucose concentration of a sample of blood. The strips comprise a plurality of working connectors, for interfacing with the meter, coupled to one or more working electrodes. The strips are of particular use in adapting multi-input meters for single input use.

68. A system for electrochemically measuring an analyte in a sample material, the system comprising:
-
a strip comprising; a reference electrode and a working electrode;
a reference connector, a first working connector, and second working connector for interfacing the strip to the measuring device;a reference link configured to electrically couple the reference electrode to the reference connector; a first working link configured to electrically couple the working electrode to the first working connector, and a second working link configured to electrically couple to the working electrode to the second working connector, and a meter comprising; a first test voltage circuit capable of applying a first test voltage between the first working connector and the reference connector; a second test voltage circuit capable of applying a second test voltage between the second working connector and the reference connector; a current measurement circuit capable of measuring a first test current between the first working connector and the reference connector and a second test current between the second connector and the reference connector. - View Dependent Claims (69, 70, 71, 72)
